Procurement Notes

Verify the specific suffix (N or S) against the design requirement, as it denotes connector gender. Confirm compliance with MIL-DTL-M3933 if military qualification is mandatory. Check RoHS status, as these components are typically non-compliant. Ensure the 2W power rating and 18 GHz frequency limit align with system specifications before procurement.

Selection Notes

Select this model when a fixed 23dB attenuation is required at frequencies up to 18 GHz. The 50 Ohm impedance matches standard RF systems. Consider the SMA interface compatibility with existing cabling. Verify that the 2W power handling meets peak and average power requirements. Compare with other M3933/16 variants if different attenuation values are needed.

Part Context

This part belongs to the M3933/16 series of fixed attenuators from Midwest Microwave. The series offers various attenuation values while maintaining consistent electrical characteristics and form factors. These components are designed for high-reliability applications in defense and aerospace sectors, adhering to strict military standards for performance and durability.

Replacement Considerations

Direct substitutes include other M3933/16 series parts with identical electrical specs but different attenuation values. Cross-reference with manufacturer datasheets for mechanical dimensions and connector gender variations. Ensure any replacement maintains the same MIL-DTL-M3933 compliance and SMA interface compatibility.
